title: 1,3-Bis(prop-2-yn-1-yl)-1H-anthra[1,2-d]imidazole-2,6,11(3H)-trione.
abstract: In the title compound, C21H12N2O3, the fused-ring system is roughly planar, the largest deviation from the mean plane being 0.084 (2) Å. The two prop-2-yn-1-yl groups are almost perpendicular to the fused ring plane, making C-C-N-C torsion angles of -103.4 (2) and -105.3 (2)°, and point in opposite directions with respect to the plane. In the crystal, mol-ecules are linked by weak C-H⋯O hydrogen bonds, forming a three-dimensional network.
